TWO AND FOUR WHEELER CARBURETOR
[attachment=22441]
What is carburetor?
A carburetor carburetor, or carburetor is a device that blends air and feul for an internal combustion engine. It is sometimes shortened to carb in North America and the United Kingdom.
Word origin:
The word carburetor comes from the French carbure meaning "carbide”. Carburer means to combine with carbon In fuel chemistry, the term has the more specific meaning of increasing the carbon content of a fuel by mixing it with a volatile hydrocarbon.
History:
A carburetor was developed by Enrico Bernardi at University of Padua in 1882, for his “Motrice Pia”, the first petrol combustion engine prototyped on 5 August 1882.
A carburetor was among the early patents by Karl Benz as he developed internal combustion engines and their components. The Austria automobile pioneer Siegfried Marcus invented the “rotating brush carburettor”. This was further improved by the Hungarian engineers János Csonka and Donate Bánki in 1893.
Carburetors were the usual fuel delivery method for most U.S. made gasoline-fueled engines up until the late 1980s, when fuel injection became the preferred method of automotive fuel delivery. In the U.S. market, the last carbureted cars were:
• 1990 (General public) : Oldsmobile Custom Cruiser, Buick Estate Wagon
• 1991 (Police) : Ford Crown Victoria Police Interceptor with the 5.8 L engine.
• 1991 (SUV) : Jeep Grand Wagoneer with the AMC 360 engine.
• 1994 (Light truck) : Isuzu
Principles:
The carburetor works on Bernoulli's principle: the faster air moves, the lower its static pressure, and the higher its dynamic pressure. The throttle (accelerator) linkage does not directly control the flow of liquid fuel. Instead, it actuates carburetor mechanisms which meter the flow of air being pulled into the engine. The speed of this flow, and therefore its pressure, determines the amount of fuel drawn into the airstream.
